The Bahraini Dinar was introduced as a currency in 1965, six years before Bahrain gained full independence; it replaced the Gulf Rupee at a rate of 10 rupees = 1 dinar. The Dinar is subdivided into 1,000 Fils (the singular form is also Fils); hence it is usually represented with three decimal places denoting the Fils. The 5 Fils coin is currently the smallest one in circulation, because the 1 Fils coin was only issued in 1965 and 1966 and it no longer circulates.
1965 was the only year when five fils were issued in bronze; in 1991, the metal was changed to brass. Occasionally, non-circulating legal tender silver five fils coins have also been issued as part of commemorative sets.
